I´m out of my wits here.
I´m trying to control the midi I send to an old Roland MC303 from my arturia BeatStep Pro. I need the MC303 to ONLY receive one midi channel from the BSP. As it is, when I send midi to the MC303 it receives it and plays it, but the thing is that it´s receiving midi from all three channels, and so the drum set is playing unwanted notes.
I know the way to go is to set up the midi channel in the receiving unit, but the MC303 is a digital machine and it does not allow to take the omni off. I have been researching this for weeks, and I don´t think it can be done. Maybe with sysex commands, but I don't even know where would I start doing it.
So the question is: would a midi thru splitter box allow me to send out the three midi channels separate? Wouldn´t it simply send a mirror of what´s coming in to the outs?
